It hangs around 198.1 seconds.
Pid 2582 is X.
Pid 2750/2751 is mythfrontend.
I'm attaching some output from libxvmc for the time period above. Output
contains mainly indications on which public functions in viaXvMC.c are
called and also some messages from the lower layer. Locking messages are
from hwlLock/hwlUnlock. The timestamps in this log aren't 100% accurate,
but should give a rough indication of current time.
Nothing exceptional in the log as far as i can tell. No indications of any
XvMCDestroySurface calls. All non-static function in viaXvMC.c log when
called (except for a few which only have a single return statement).
I'm running trunk openchrome and ubuntu's 2.6.31-17-generic kernel.
One strange thing I see is that prior to the freeze the video rendering
slows down and frames seem to be rendered in reverse/random order. Do you
see that as well? In my video there's scrolling text as the freeze happens
and the second before the freeze the text starts to move back where it
came from and jump a little back and forth. So something bad seems to
happen a few seconds before the crash.
